g) Input Systems and Output Systems
There are various input and output systems which are used to capture and view data on
computer systems. Developments in technology have brought about new tools which
are now used to capture and access information.
In addition to traditional input systems such as keyboards, monitors, scanners, and
mouse, other forms of input systems have been introduced in office environments
and have changed the way we capture data. Touch screens are now widely used for
capturing data. Special cameras are also used to capture real-time data and convert
it into human understandable information in the form of reports and graphs. This in-
formation is captured without human intervention. Sensors can also be used as mon-
itoring devices as they are able to report on various production processes, quality
control, and status of production equipment.
Advancements in system integration have enabled automation of data input from one
system to the other with limited or no human intervention. This has made capturing
of data very easy and also provided the capability to capture large volumes of data.
Output systems have also undergone transformation in the way we access information
with the introduction of new technologies. Output systems can be used to produce
information using touch screens and converting voice output into text and vice versa.
Using new technologies, output can also be produced using automated reports, which
is immediately used as input into other systems.
Integrated systems are also able to accept output from other systems. Output from one
system may be input for another system. This is now common in most integrated
systems as it ensures efficiency in data capture and also accuracy of input. Most en-
terprises rely on the use of complex and feature-rich ERP systems with enhanced
system integration features.
The benefits of new input and output systems are efficiency, speed, and accuracy. New
technologies, despite the benefits, have brought about new risks to the enterprise. IS
auditors need to ensure that possible risks are identified and recommend to manage-
ment effective ways of mitigating these risks.
The audit objectives for auditing input and output systems may include testing:
